HORSE DRIVER AND GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 536,714, dated April 2, 1895.

Application filed August 21,1894.

T all whom it may concern.:

Be it known that we, HENRY A. ARNOLD and CLIFTON S. ARNoLD,citizens of the United States, residing at Lake Geneva, in the county of Walworth and State of Wisconsin, have invented a new and useful Horse Driver and Governor, of which the following is a specification.

Our invention relates to an improvement in a horse driving and governing device for 'use in connection with horse powers, the objects in view being to provide means for urging forward lagging horses and for restraining a horse that attempts to exceed a certain speed in orderto provide for a uniform movement of the mechanism.

Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly `pointed out in the appended claims. p

In the drawings :H-Figure lis a perspective View of a mechanism embodying our .invention. Fig. 2 is a transverse section on the line 2--2of Fig. 1. Fig. 3-is a detail section of the hub to which are connected the driving arms, said section being taken at right angles vto the plane of Fig. 2. Fig. 4 is a detail view in perspective of the same with the parts detached. Fig. 5 is a bottom plan view of the escapement-device. Fig. 6 is a longitudinal section of the same. Fig. 7 is a detail View in perspective of one of the driving arms and attached Whip'or driving-bar.

Similar numerals of reference indicate corresponding parts in all the figures ofthe drawings.

ldesignates a base, upon which is mounted the annular master-gear 2, provided with internal teeth 3, which mesh -with a pinion 4 carried byavertical spindle 5. This vertical spindle is geared at its lower end by means `^of the miter-gears 6 and 7with a power-shaft 8, and this power-shaft carries a large gear 9 meshing with a similar gear or pinion 10 upon an'adjacent parallel power-shaft 11. It will be seen that the power-shaft 1l receives its motion from the shaft 8 and rotates at a higher rate of speed. Attached tothe master-gear are the' draft-sweeps 12, provided with the brace-rods 13, and carrying the chains 14 for senti No. 520.913. (No model.)

the attachment of Whifllet'rees for one or two horses on each sweep. I

Risingfrom the base 1 is a stationary vertical post supporting the escapement wheel 34, the wheel being firmly held in place on the top of the post by means of bolts passing down through a web across the center of the wheel flush with the lower side of said wheel, and outside of said post and on down through the cross-beam 23, the cross frame being bolted to the base 1.

Rising from the center of the escapementwheel is a stationary vertical arbor 15, upon which are mounted by means of the hub, the radial driving-arms 16, one of which is connected by means of a chain or other iiexible device 17 to an escapement device 18, which is similar tothat shown and 'described in our patent issued July 17, 1891, No. 522,956, said chain or flexible connection 17 being passed around a direction pulley 19 carried by the draft-sweep in rear of the driving-arm to which the. extremity of said chain is attached. This chain is providedwith a terminal hook 20 for engagement with one of a series of eyes or keepers 2l on said driving-arm, for a purpose hereinafter explained, and connecting said driving-arm to the draft-sweep in advance thereof is a tension spring 22, which is adapted to drawl said driving-arm forward or in the direction of movement thereof, in order to communicate motion from the draft-sweeps to the driving-arms and hold the restraining chain 17 taut.

The arbor 15 extends up from the center of the escapement-wheel, and the inner ends of the driving-arms are attached to a rotary crown or hub 24, which is mounted for free rotation upon said arbor. This crown or hub consists of a lower cap 25 provided at its periphery and upon its upper side with a series of seats 26 for the reception of said drivingarms and an upper cap 27 which is adapted to fit over the lower cap and bear upon the upper sides of the driving-arms to hold the latter in the seats of the lower cap, said upper cap being adjustable by means of the bolts 28 and engaging nuts 29. comprising the crown or hub, are hollow or dish-shaped, and in the cavities thereof are arranged adjustable disks 30 provided in These caps,

IOO

' detent or escapement 37 carried by saidspider of these disks the inclination ot' the drivingarms may be altered as may be desired to suit the height of a mounted or down power and other requirements.

The escapement device above referred to, comprises a fixed or stationary escapementwheel 34 secured to the top ofthe supporting post (see Fig. 2), a spider 35 loosely mounted upon the escapement-wheel and having an arm 36, to which is attached one end of the chain or flexible connection 17, and 'apivotal in position to engage the teeth of Ythe escapement-wheel, whereby as the spider is rotated upon the escapement-whee'l around a collar 30 of said wheel 34 as a center, said detent or escapement vibrates continuously by reason of its engagement with the teeth of the escapement-wheel. In order to provide for a comparatively slow vibration of the detent or escapement, a bar 38 is attachedto the'detent or escapement and is provided at itsextremities with adjustable weights 39. Byaltering the points of attachment of these weights the resistance olfered by the detent or escapement'to the forward rotation ot the spider may be varied. y Y

Pivotally connected to thed riving-arms are driving-bars or whips 40, which are fitted `at j their pivoted ends in pockets or brackets 4l,

whereby when extended said driving-bars or whi ps are held substantially in alignment with the driving-arlns. These driving-bars or whips preferably consistot a light bar of wood, to the front side ofiwhic'h is attached a strip 42 of leather or similar inateriahbearing a series of points or spurs 43. Attached to the extremities of the driving-arms are 'reinholding arms 44`to hold the reins 45 in the proper position over the horses, and adjacent to these rein-holding arms are keepers or hooks 46, with which the reins may be en-1 gaged when the proper lengthot such reins has been attained. When a pin is inserted in thechain 17 directly behind the guide-puh ley 19, the driving-arms 16 are rmlyfheld in a retracted position, and the machineis at rest, so that when the horse or horses 'are attached to the drat'tfsweep by 'means ofthe whiletrees, and their lines fastened tothe rein-holding arms 44 and tied by their lead straps so that they cannot swing out, they are securely held from going.

When the pin is removed from "the chain behind the guide-pulley 19,'tl1e driving-arms are drawn forward toward theho'rses by the tension-spring 22. If the latter lstart immediately the forward motionvwhichihs in iparted fered to the operating Varm 18b'y vthe operation of the escapement devicewill retard the motion of the connecting chain 17 and of the drivingarms attached thereto, removing them from contact with the horses. The drivingarms,with their whips 40, are held out of contact with the horses by means of the escapement 4device when the horses are moving at the desired rate of speed, which is predetermined, and the hook 2O adjusted in the eye for such speed. The driving-arms are held in a retracted position so long as the horses maintain an approximately steady speed; but if their movement is increased the driving lines attached to the rein-holding arm 44 will be retarded owing to the constant resistance ofthe escapement device, thus partially checking the horses; and itl one or more of the horses lag or do not keep up to the speed of the mechanism, the whips will overtake them and urge them to agrea'ter exertion.

It the hook 2O is removed to an eye nearer the inner end of the driving-arm 16, the speed is somewhat increased by the increased leverage that the spring 22 has over the escapement device through the connecting chain; andwhen the hook is removed to an eye nearer the outer end of said driving-arm, the speed is decreased by the decreased leverage. The speed can further be changed by removing theweights 39 on the escapement lever 38 toward or from the escapement pawl, as described.

It will he understood that when not in use or not required the driving-arms or whips may be vturned inward so as to be out of reach of the horses.

It will be understood that in practice various changes in the form, proportion, and the minor details of construction may be re- Sorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.
